How to have threads appear above forums and not below them?

Ok here's the deal.
I have set up my categories to also function as a forum.
So when you go to a category you not only see its list of forums, but after all the forums are listed you also see the forums threads.
I want to reverse that order.
I want the threads to appear at the top, and the forums to appear below the threads.

And as a bonus i want to be able to limit the amount of threads that show up to just 5 or 10 before a person has to move on to the next page of threads... but only for threads within a category.
